Columbia continually evaluates additional ways to effectively and efficiently meet the needs of our clients.  As a part of that, we have invested in a real-time view pole camera to improve our deliverables and provide our clients with the highest quality product.   This equipment will allow us to quickly inspect manholes and pipes on the site.  It is equipped with a high beam light, an extreme zoom HD camera, and a laser that measures distance.  This new equipment gives provides the following abilities:

  • Determine pipe condition quickly with videos and pictures easily provided the client for reference.
  • Inspect pipes that a crawler cannot go into due to pipe condition or standing water.
  • Determine accurate locations of buried structures using the camera and the laser rangefinder.
  • Improve quality control by allowing desktop verification of survey data.
  • Minimize risk by limiting need for confined entry.
